Crews cleaned up a landslide on Pioneer Highway, south of the town of Stanwood. Know which areas are safe and how to reach them in an emergency. Roadway is fully blocked. The USGS also worked with partners to obtain and study soil samples from the landslide area to better understand the landslides characteristics and behavior. menu. This work entailed making approximately 1,400 on-site observations of the landslide surface to reconstruct the displaced geology of the landslide deposit in order for the mobility of the landslide to be deciphered. The area overrun by the landslide was about one half square mile, and the landslide moved about 18 million tons of sand, till, and clay. The findings of this work will be published in the coming months and are anticipated to help update and develop models that better capture the true behavior of these types of landslides.
